WIRE-BARBING MACHINE.

SlfECIFICATION forming part of Letters Patent No. 249,735, dated November 22, 1881.

Application filed July 5, 1881.

To all whom it may concern Be it known that I, GEORGE O. BAKER, of Des Moines, in the county of Polk and State of Iowa, have invented an Improved Wire-Barbing Machine, of which the following isa specification.

My machine is one of that class through which fence wires or cables are moved longitudinally from one reel to another and barbs formed thereon at regular intervals of space by coiling wire barb-pieces around the fence wire or cable. It is constructed as hereinafter fully set forth, and the novelty of my invention is clearly pointed out by my series of claims.

Figure 1 of my accompanying drawings is a top view, and Fig.2 a side view, of my complete machine, and together they clearly show the relative positions of the various groups of operative mechanism employed therein.

A represents a base or bench, that may be made of wood or metal in any suitable way. A is an extension at its rear end. A represents an extension of the frontend, adapted to support a reel or spool of fence-wire.

B B represent extensions or brackets at the opposite sides of themain frame, base, or bench, adapted to support spools of barb-wires.

B is a driving-shaft, mounted on the rear portion of the base A in a transverse position by means of suitable posts and bearings fixed on top of the base.

B is a belt-wheel, fixed to the shaft B outside of the base. B is a loose belt-wheel on the same shaft, adapted to facilitate the connecting and disconnecting of the machine with an engine. B is a balance-wheel fixed on the end of the shaft and contiguous to the loosebelt-wheel. B is a balance-wheel fixed on the opposite end of the same shaft.

0 is a rotating shaft, mounted in a horizontal and transverse position upon the rear end of the extension of the base or frame A by means of suitable bearings fixed thereto.

0 is a ratchet-wheel fixed to the shaft 0.

O is a lever of the first order, that has a toothed sector on its lower end and short arm, and is pivoted to the shaft 0 outside of the ratchet-wheel G a is a pawl, pivoted to the top end and long arm of the lever 0 to engage the ratchet Wheel.

(No model.)

O is a lever of the third order, that has a segmental rack at its top end, and is pivoted at its lower end by means of a fulcrum fixed to the frame or base at a point immediately below the shaft 0. This combined lever and rack has a longitudinal slot, to, by means of which power is applied to it at different points, for the purpose of governing the length of its vibrations, and thereby the revolution of the shaft 0, that carries a spool, upon which the'barbed fence-wire is wound by means of intermittent rotary motions transmitted to the shaft 0 from the shaft B through the medium of my devices for controlling the movement of the fencewire and regulating the spaces between the barbs.

a" is a pitman, that connects the lever O with the balancewheel B One end of said pitmanis secured tothebalan-ce-whcel bymeans of a wrist-pin, and the other end is secured to the lever bymeans of a bolt that slides in the slot a.

b is a rock-shaft, mounted in a horizontal and transverse position by means of suitable bearings attached to the front and lower portion of the extension A of the frame. It has an arm, I), that extends at right angles rearward, and is flexibly connected with the rear end of the pitman a by means of a straight link, I), as clearly shown in Fig. 2. It also has a lever-handle, b, that extends at right angles upward to engage a rack, D, that is fixed to the frame A in any suitable way and position, so as to allow the lover I) to slide thereon and to be fastened thereto by means of a movablepinthatcanbeinserted in oneofaseries of perforations in the rack or some other suitable fastening device. By adjusting the lever b relative to the rack D the arm I) is readily raised or lowered to adjustthe position of the pit-man relative to the combined lever and rack G By an upward movement of the end of the pitman the stroke'or length of vibration of the lever G is increased, and by means of the combined lever and toothed sector 0 and the ratchet-wheel O the fractional revolution of the shaft 0 and the spool carried thereby is increased accordingly, and diminished byareverse movement of the same end of the pitman. By this means the shaft and spool can be revolved an equal distance at each intermittent motion, and that distance decreased at each successive layer of barbed wire Wrapped upon the spool. As the circumference of the coils increase upon the spools the fractional and intermittent revolutions of the shaft can therefore be diminished accordingly, to preserve nniformity in the intermittent movement of the fence-wire drawn by the spool, and as required to fix the bat bs thereon at regular intervals.

c is a bevel-gear wheel fixed on the drivingshaft B to transmit power and motion therefrom to the barb-feedin g, barb-cuttin g, and barb-formin g mechanisms.

1) is a rotating shaft, mounted upon the base A horizontally and at right angles to the driving-shaft B c is a bevel-gear wheel fixed on the rear end of the shaft D toengage the wheel 0.

cis a gear-wheel fixed on the front portion of the shaft D to transmit motion to a parallel shaft.

Nos. 1, 2, and 3 are parallel shafts, mounted upon the base A immediately over each other and in a vertical line by means of posts d and d, that are fixed upon the base A.

Nos. 4, 5, and 6 are gear-wheels of uniform size on the shafts Nos. 1, 2, 3. N0. 4 is fixed to the lower shaft, No. 7, and engages the wheel 0 on the shaft D No. 6 is fixed to the upper shaft, No. 3, and No. 5 is placed loosely upon the center and tubular shaft, No. 2.

To. advance the barb-wires from the spools on-the extensions B at regular intervals by means of the continuous rotary motion of the shaft No. 7, a cam,f, is fixed to the shaft, to impart a reciprocating motion to a double rack.

f f are the parallel bars of the rack, mounted in bearingsf, that are fixed to the base A. These rack-bars are connected by a crosspiece, f, and from the center of the cross-piece project upward two studs, f, that are alternately engaged by the camf, as required to move the rack-bars in opposite direction at regular intervals.

d is a post, fixed to the base A in line with the posts d and d.

d are shaft-bearings, formed on or fixed to the sides of the post (1, to support vertical rotating shafts g and g in parallel positions, as clearly shown in an enlarged detail view,Fig. 10.

g are combined pinions and ratchets, placed loosely on the lower portions of the shafts g, to be engaged by the toothed ends of the rackbars f.

g are pinions, fixed to the shafts 9 above the combined pinions and ratchets g in such a manner that spring-pawls it, carried on their under sides, will engage the ratchets and lock the loose pinions g" and the fixed pinions together, so that a rearward motion of the rack-bars f will cause theshafts gto be revolved. A reverse motion of the same bars will revolve the combined pinions and ratchets g, but allow the shafts g to remain stationary.

g are gear-wheels fixed to the shafts g and g, to transmit motion from the one to the other, as required, to actuate thefeed-rollers h at their top ends jointly, and at regular intervals to advance the barb-wire to the cutting and coiling mechanism.

Figs. 3, 4:, and 5 are enlarged detail views,

illustrating the construction and operation of my barb-cutting mechanism combined with the post d. In Fig. 3 the rear side of the post is shown, and 01 represents flanges or re-enforcing ribs at its edges.

t is a circular opening, through which the fence-wire is passed. is a short rock-shaft, that extends through a corresponding hole in the lower portion of the post, and is secured to the post by means of a bearing, 70, that is bolted against the face of the post.

It and k are short arms, that are formed integral with a hub that is rigidly fixed to the shaft 70 by means of a collar and key. Each a as a stud-roller, I, projecting at right angles from its free end, to engage a cam, I, that is fixed on the shaft D As the cam l is revolved it engages the arms k and k alternately and rocks the shaft back and forth at each revolution.

l is a pin or stud on the front end of the shaft 70, in an eccentric position, and performs the function of a cam by engaging the upper edge of an orifice, l, formed in the cutter-car.- rier 1, that slides in a panel formed in the front face of the post (1. The position of the cutter-carrier and the form of the orifice into which the eccentric or stud 1 projects and at each revolution of the cam l forces the cutter-earrier upward are such as are required to actuate the cutters at regular intervals.

I am aware that a rotating driving'shaft has been combined with a euttei carrier by means of an intermediate cam-wheel, to impart a reciprocating motion to the cutters at regular intervals; but my manner of combining a rockshaft direct with a cutter-carrier by means of apin on the end of the shaft is novel and greatly advantageous.

Fig. 6 is afront face view of thepost d, showing the cutters and jaws combined therewith. m m are steel cutters in the form of straight bars, that have portions cut away from their upper ends to make them triangular in their cross-sections, as clearly shown in Fig. 7, which is taken by looking downward from the line as w of Fig. 6. These cutters are placed against the sides of a panel formed in the face of the cutter-carrier 1,and on opposite sides of one of my reciprocating jaws m, and retained in place by means of a plate, m", that is placed across the panel and fastened to the face of the cutter-carrier by means of screw-bolts and triangular-shaped wire-guides m, fixed on the top surfaces of the cutter-carrier.

m is a detachable cross-bar, fitted in corresponding grooves, a, cut in the sides of the cutter-carrier, to intersect the panel in the center.

a are set-screws passed upward through the bar m to support and adjust the cutters m. A corresponding cutter-carrier is placed in the upper portion of the panel in the post d and rigidly fixed by means of screw-bolts The bearings formed by means of the cutters allow the jaws between the cutters to move up and down at regular intervals, as required, to hold the fence-wire rigidly while the barb-wires are coiled around it. (Jams r on the ends of the shafts Nos. 1 and 3 (shown in Fig. 2) engage the pins 7', that project laterally from the ends of the jaws, and thereby open and close them at each revolution of the shafts; and when the jaws are closed upon the fence-wire notches 1" (clearly shown in Fig. 8) at the same time engage the wire barb-pieces, and thereby each jaw holds one end of a barb firmly to the fence-wire, while the free ends of the same barb-pieces are carried around the fencewire and their central portions coiled to clamp upon and fasten to the fence-wire.

s is a detachable head on the end of the tubular shaft No. 2, through which the fencewire is advanced; It is angular in shape, as clearly shown in an enlarged perspective View, Fig. 9, and has projections s on its front face to engage the barb-pieces. These projections are in diagonal positions relative to the square face of the head, and each has triangularshaped faces 8 and s, that incline in opposite directions, as required, to facilitate the passage of the barb, so that it will enter between the square shoulder 8 of the projection s and the fence-wire, and also the jaw m. This head 8 has a screw-shank similar to the head shown in my patent bearing date July 22, 1879, No. 217,637; but the peculiar shape of its front end, as clearly shown in the enlarged view, Fig. 9, adapting it to be operated in concert with automatic barb-feeding mechanism to produce a solid barb, is novel and advantageous.

Intermittent rotary motion is imparted to the tubular shaft No. 2 and the head 8 by means of a mutilated gear-wheel, t, on the front end of the driving-shaft D and a pinion, t, on the shaft No. 2, as clearly shown in Fig. 2. A segmental flange, t, on the mutilated gearwheel t engages a cam, t, on the pinions t, to hold the pinion and tubular shaft and its head s stationary while the barb-wires are bein g advanced and cut.
